Run Python/Django Management Command from a UnitTest/WebTest

Question

We have a bunch of commands in our Django site, some that are administrative and some that run on cron jobs that I can't figure out how to test. They pretty much look like this:

# Saved in file /app/management/commands/some_command.py # Usage: python manage.py some_command from django.core.management.base import NoArgsCommand class Command(NoArgsCommand):     def handle_noargs(self, **options):          # Do something useful 

And I have some tests, which look like this:

import unittest from django.test import TestCase from django_webtest import WebTest  class SomeTest(WebTest):     fixtures = ['testdata.json']      def setUp(self):         self.open_in_browser = False         # Set up some objects      def test_registration(self):         response = self.client.get('/register/')         self.assertEqual(response.status_code, 200)         form = self.app.get('/register/').forms[1]         # Set up the form         response = form.submit()         self.assertContains(response, 'You are Registered.')         if self.open_in_browser:             response.showbrowser()          # Here I'd like to run some_command to see the how it affects my new user. 

In my test (where I have the comment) I'd like to run my NoArgsCommand to see what happens to my new user. I can't find any documentation or examples on how to accomplish this. Also note that my test environment is a SQLlite DB that I create from scratch in memory, load some fixtures and objects into and run my tests, so as much as I'd like to setup the data in a real DB, then just run my command from the command line, I can't, it's far too time consuming. Any ideas would be greatly appreciated.

Django documentation on management commands might help, it describes how to call them from python code.

Basically you need something like this:

from django.core import management management.call_command( ... )
